Method Summary

boolean	canParticipateInSerialization() Indicates whether the data of this element eviction instance can participate in serialization of the element as a whole.
ElementEvictionData	clone() Creates a clone of the eviction data
long	getCreationTime() Get the element's creation time.
long	getLastAccessTime() Gets the last access time.
void	resetLastAccessTime(Element element) Resets the last access time.
void	setCreationTime(long creationTime) Sets the element creation time.
void	updateLastAccessTime(long time, Element element) Updates the last access time.

Method Detail

setCreationTime

void setCreationTime(long creationTime)

Sets the element creation time. Note that this is optional to implement and might result in a no-op.

Parameters:

creationTime - the new element's creation time

getCreationTime

long getCreationTime()

Get the element's creation time.

Returns:

the element's creation time in seconds

getLastAccessTime

long getLastAccessTime()

Gets the last access time. Access means a get. So a newly created Element will have a last access time equal to its create time.

Returns:

the element's last access time in seconds

updateLastAccessTime

void updateLastAccessTime(long time,
                          Element element)

Updates the last access time.

Parameters:

time - the new last access time

element - the element for which the last access time is set

resetLastAccessTime

void resetLastAccessTime(Element element)

Resets the last access time.

Parameters:

element - the element for which the last access time is set

clone

ElementEvictionData clone()
                          throws CloneNotSupportedException

Creates a clone of the eviction data

Returns:

a clone of the eviction data

Throws:

CloneNotSupportedException

canParticipateInSerialization

boolean canParticipateInSerialization()

Indicates whether the data of this element eviction instance can participate in serialization of the element as a whole.

Returns:

true when the data can participate in serialization; or false otherwise
